There are some missing responses on 'page.on("response") when I invoke 'page.goto()'.

• Puppeteer version: 1.6.1
• Platform / OS version:mac/sierra 10.12.6
• Node.js version:8.9.0

I'm using puppeteer.connect() to reuse a browser.
I found out that some of the responses were missing when I called page.goto() again.

What steps will reproduce the problem?

const puppeteer = require('puppeteer');

const excludeResources = ['stylesheet', 'image', 'media', 'font', 'manifest', 'other'];

async function test(browser) {
    const page = await browser.newPage();
    await page.setRequestInterception(true);
    await page.setCacheEnabled(false);
    page.on('request', request => {
        if (request.resourceType() === 'document')
            console.log("request - resource type: " + request.resourceType() + ", url: " + request.url() + ", nav: " + request.isNavigationRequest() + ", redir: " + request.redirectChain().length);

        if (excludeResources.indexOf(request.resourceType()) > -1)
            request.abort('aborted');
        else
            request.continue();
    });

    page.on('response', async response => {
        if (response.request().resourceType() === 'document')
            console.log("response - resource type: " + response.request().resourceType() + ", url: " + response.url());
    });
    await page.goto('https://www.daum.net');
    await page.close();
}

puppeteer.launch({headless: false, dumpio: true}).then(async browser=> {
    console.log('First Time ---------------');
    await test(browser);
    const wsEndpoint = browser.wsEndpoint();
    browser.disconnect();

    console.log('\nSecond Time ---------------');
    puppeteer.connect({browserWSEndpoint: wsEndpoint, ignoreHTTPSErrors: true}).then(async browser=> {
        await test(browser);
        browser.close();
    });
});

execution result

First Time ---------------
request - resource type: document, url: https://www.daum.net/, nav: true, redir: 0
response - resource type: document, url: https://www.daum.net/
request - resource type: document, url: https://logins.daum.net/accounts/toploginform.do, nav: true, redir: 0
request - resource type: document, url: https://lithium.daum.net/provide/v3/shopbox, nav: true, redir: 0
request - resource type: document, url: https://shop-redapi.daum.net/red-apigate/daumtop/v3/planmall, nav: true, redir: 0
response - resource type: document, url: https://logins.daum.net/accounts/toploginform.do
response - resource type: document, url: https://lithium.daum.net/provide/v3/shopbox
response - resource type: document, url: https://shop-redapi.daum.net/red-apigate/daumtop/v3/planmall

Second Time ---------------
request - resource type: document, url: https://www.daum.net/, nav: true, redir: 0
request - resource type: document, url: https://logins.daum.net/accounts/toploginform.do, nav: true, redir: 0
response - resource type: document, url: https://logins.daum.net/accounts/toploginform.do
request - resource type: document, url: https://lithium.daum.net/provide/v3/shopbox, nav: true, redir: 0
request - resource type: document, url: https://shop-redapi.daum.net/red-apigate/daumtop/v3/planmall, nav: true, redir: 0
response - resource type: document, url: https://shop-redapi.daum.net/red-apigate/daumtop/v3/planmall
response - resource type: document, url: https://lithium.daum.net/provide/v3/shopbox

What is the expected result?
I want to get the same response every time I ask for all the requests.

What happens instead?
As you can see from the results, 'response - resource type: document, url: https://www.daum.net/' is in the first attempt, but not in the second attempt.
I think this result came out because the browser was caching the response inside.

The problem seems that have been solved after applying #2954 fix.

Dupe of #2970.

Edit: this is #2970.

[aslushnikov]

Everybody: this is now fixed on tip-of-tree; it could be installed with npm i puppeteer@next.
We'll release v1.6.2 that addresses this regression shortly.
